Process Validation Master Planning DMAIC Fusion

Description

Process validation is a risk management verification activity for medical device and pharma companies. DMAIC is a well established methodology for improving process reliability, improving businesses and solving problems. This presentation discussed a logical fusion of these approaches. It includes a description of the validation life cycle. The business case for good validation is illustrated graphically. Contact us at ARVExcellence.com if you would like a copy.

• Requirement:
“establish documented evidence which provides a high degree of assurance
that a specific process will consistently produce a product meeting its
predetermined specifications and quality attributes.” [1]QSR 820.3

(Time and cost)
• Statistical validity
– minimum n to test Normality
• Wider Interval – Less likely to fit in specification
• Width of Tolerance Interval
– X-bar +/- ks
k = f(n, assurance, proportion)
– Lower n , wider interval
– Higher Risk Index, greater proportion, wider interval
